Homemade table saw – a necessary and useful tool in the arsenal of DIY. It is especially necessary for those who work a lot with wood. To make a circular saw on their own, enough to have a great desire, the necessary tools and be able to work with metal.
Circular saw, with his own hands structures can be stationary or desktop model. At its core is the same. They differ devices only frame height. What height do will depend on the intensity of use of the workplace. If the saw is rarely used, it can be done in a desktop variant. If necessary, the design can be dismantled and make space in a workshop for other works. If the master is constantly working with wood, he is more suitable for stationary circular saw.
Stationary design consists of several main components: a table, a gear drive motor, an adjustable lateral abutment and the shaft.
For its production will be needed:
The sheet metal is not less than 8 mm.
Metal corner 45×45 mm.
The metal disc with teeth (diameter 400 mm).
Cut or plastic laminate.
Circular saw with their own hands will be made much easier if you first make a drawing of future construction, and to specify all the required dimensions. All items are made according to the drawing, and then going into the frame using a welding machine.
Assembling a stationary structure
The main part of the saw – table. Worktop should be made of sheet metal. Its size depends on the preferences of the master. The main thing that a circular saw with his own hands was stable and it was convenient to operate. If you need additional space to install other devices, the surface can be closed by a thick sheet of plywood
Particular attention should be paid to the height of the guide. Most conveniently, when the guide appears above the table of 120 mm. Experience has shown that with this arrangement, it becomes possible to handle not only the board width, and thickness.
The surface of the countertop
For the production of a guide on the circular saw will need 2 metal angle segment and a clamp that is welded to it. Metal detail deliberately done in two parts corner. Solid area will be carried out at the saw. It corners with bolts and screws needed to fasten a piece of wood, and on it to fix a piece of plastic or a laminate of 120 mm. laminate segment length must conform to the length of the table. This part should be exposed at an angle of 90 ° relative to the countertop.
Circular saw with his own hands must be adjustable in height. In some designs, you can adjust the table, but it is more convenient to work, when you can raise and lower the saw itself.
To install the motor and shaft needs a common platform. It should be installed on the same axis as the rocker. It is fixed segment bolt diameter of 15 mm, which is welded to it. On the side of the blade need to weld the metal plate, wherein the pre-make a hole. His form has to be elongated along the rocker. Through it will be a bolt, which should be screwed lamb with handles. Lock blade ready. If there is a need for height adjustment, then unscrew the thumbscrew, I saw exposed on the line, and the lamb is twisted back. When using a disc diameter of 400 mm can be processed boards 240 mm
By the wooden blocks, attach a piece of laminate, which angle should be 90 ° to the table top.
Circular saw with their own hands can be made in manual form. The easiest way to make it out of the grinder, making its structure some improvements. On grinders to install and handle axial sliding emphasis.
To make a sliding emphasis will be needed 2 corner segment. They are located on the sides of the disk with the teeth, which replaces the grinding wheel. The corners are fixed with a clearance 3-4 mm. Ahead and behind, they are connected by bolts and nuts. For clearance must use washers. The lower edge corners shall be rounded. Because of this they will not cling to the processed items.
Circular saw with his own hands from the grinder is equipped with a sliding stop. On the clamp body is secured. It is done from the metal strip. Screed it should be placed at the bottom. It attached ribbon strip galvanizing of a minimum thickness of 1-1,5 mm, which is first necessary to make a hole for the bolt sliding stop. With goals set gaps between the working portion and the side portions of the stop. The gaps should be the same size.
Choose the right tools:
By the gear housing is attached axial handle. To this end, the gearbox disassembled in order to be able to determine at what points to make 4 small holes for the bolts. The handle is made of a rod or pipe section and must be shaped bracket. Its width is slightly wider than the palm of the master. At the ends, which it will be attached to the gear unit, it is necessary to drill holes for the bolts. Flared ends of the tube is not necessary that the handle does not buckle during operation.
Under the handle must be secured segment of the rod or tube protruding. The end of the tube razvaltsevat and make a hole for the axis in the thickness of 4-6 mm. The hole must be larger than 4 mm. To work comfortably between the rod and the handle is left a gap of at least 100-150 mm.
The next step – making the adjustment rod. This will require a length of rod with a diameter of 4-6 mm. The end of the pipe is curved in the form of loops slightly flared. By means of washers on the front end of the stop is set equal clearance along the entire length.
That part of the rod that will go into the hole on the handle, shall be equipped with thread. Before inserting the rod should be screwed on her nut. Another nut is screwed after assembly. Nuts will provide adjustment of cutting depth. If necessary, they need to let go or pull.
Circular saw, with his own hands collected from the grinder can be mounted on the frame. For its production will require round pipe or rod in the 14-20 mm diameter. They bend the letter “P”. On the cross-beam mounted rocker arm. The lower part of the frame, curved horizontally is fixed to the table by means of bolts or screws. To give greater stability of the structure, it is necessary to fix the additional struts.
The oscillating lever is put on the horizontal bar. It is made from two pipe segments by welding them in a letter “T”. The upper part should be cut lengthwise into two halves. After it is put, it is necessary to seal it with clamps. To stem with clamps attached manual circular saw, with his own hands made of grinders.
